The entrance to the church is surmounted by the inscription SAPIENTIA AEDIFICAVIT SIBI DOMUM (Wisdom has built herself a home) and a curious image of an eye surrounded by an interlocking circle and triangle.
The all-seeing eye is one of the symbols of freemasonry and both the architect and the patron (a member of the Baffo family) of the church were freemasons.
Temanza's ashes are interred in La Maddalena.
